NORTHAMPTON — Police arrested a 13-year-old Northampton boy Thursday after he allegedly beat another boy in the face with a skateboard, causing “substantial injuries” that may require plastic surgery, police said.

Police are also seeking a third teen who was involved in the fistfight but fled before police arrived.

Det. Lt. Kenneth Watson said the 14-year-old victim was taken by ambulance to Cooley Dickinson Hospital before being transferred to Baystate Medical Center. His injuries are not life-threatening, Watson said.

Watson said that around 4:30 p.m., the victim and the boy who was arrested got into a fight at the Meadowbrook Apartments on Bridge Road. The third unidentified boy jumped into the fray and also assaulted the victim. The teen who was arrested then picked up a skateboard and hit the victim repeatedly in the face with it, Watson said.

Police did not identify the alleged attacker, who was arrested on a charge of aggravated assault and battery with a dangerous weapon, because he is a juvenile. Information about the victim’s condition was also unavailable because he is a juvenile.

Watson said police are still investigating the incident and actively seeking the second alleged attacker.

Animals. Simpy amazing- the mother of this thug was outside of the apartments yelling at her son to keep beating the victim. All because her son wanted some headphones. The kid should be taken away and the "mother" should be locked up
